I’m up grading my tank to a 37gallon. I was wondering if I could put my red tail shark in a 10gallon tank until the new tank is set up? It would be by itself in the 10 gallon. Is this possible?

My black moor has white spots on the fin and my red tail shark is grey with no red. Please give me direction to figure this out. This is a new tank 3 weeks old.
